Overcurrent circuit breaker S 311 1P B 10A 10000A TX3 404082

Overcurrent circuit breakers S 310 series – reliable installation protection

The S 311 1P B 10A overcurrent circuit breaker is a protective device that protects electrical circuits against the effects of overloads and short circuits. It belongs to the advanced TX³ series, characterized by high reliability and ease of installation. It is one of the key devices in every safe and functional electrical system, both in residential and commercial buildings.

Design and application

This circuit breaker, with a rated current of 10A and characteristic B, is designed to protect lighting circuits and socket outlets. Characteristic B means that the circuit breaker reacts quickly to current increase, which is particularly important in the case of inductive or capacitive loads. Mounting is done on a TH35 rail, which ensures stability and easy integration with other installation elements. Compact dimensions (width 1 module, depth 44 mm) allow for efficient use of space in the switchgear cabinet.

Key features and benefits

• High breaking capacity: The rated breaking capacity Icn is as high as 10 kA at 230 V and 10 kA at 400 V, which guarantees effective protection even in the event of serious disturbances.
• Characteristic B: Provides a quick response to current increase, protecting sensitive electronic devices and preventing damage to the installation. Allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.
• Easy installation: The lower latch and terminal covers facilitate and speed up the installation and connection of wires.
• Expandability: Compatibility with additional auxiliary equipment (auxiliary contacts, undervoltage releases) allows you to adapt the circuit breaker to specific installation needs.
• Safety: Compliance with EN 60898-1 and EN 60947-2 standards ensures a high level of safety. Protection class IP20 protects against touching with fingers and against the ingress of solid objects with a diameter greater than 12.5 mm.
• Durability: Made of high-quality materials guarantees long life and reliable operation for many years – mechanical endurance is as many as 20,000 switching cycles.

The rated current is 10 A, the tripping characteristic is B, and the breaking capacity at 230V/400V is 10 kA. The circuit breaker occupies a width of 1 module and is designed to operate at a rated voltage of 230 V.

The S 311 TX³ circuit breaker is a solid solution for every installer and user looking for reliable electrical protection. Its compact size, easy installation and high quality workmanship make it an ideal choice for a variety of applications.
